New clashes broke out Friday between masked protesters and police in downtown Washington, blocks away from the route of the parade which was about to start in honor of newly sworn-in US President Donald Trump. Some 400 to 500 protesters hurled objects at police in riot gear, who responded with tear gas, in the second outburst of violence in the space of a few hours. Washington police said they had arrested more than 90 people in the morning period over acts of vandalism committed on the fringe of peaceful citywide demonstrations being held against Trump's inauguration. By Friday evening, a total of 217 people had been arrested.
